I have 2.5 USB HDD Transcend StoreJet 25M (TS320GSJ25M) with SAMSUNG HM321HI Firmware: 2AJ10001 inside.
If the drive is formated as FAT32 - WDTV detects it - everything is fine.
If I format it as NTFS (using Transcend utility or Windows XP) my WDTV does not detect it (No storage present). The USB HDD drive is safely removed from desktop of coarse.
I think, I've found the reason of this. It is nonstandard block size of USB HDD. It is 4096 bytes instead of 512. Many linux programms and distros on desktop (Gparted - for examble) work incorrectly with this block size. Here is a screenshot

Here is the translation for the first line of "fdisk -l" output
Note: sector size is 4096 (not 512).
Here is a report on the HDD from HDDScan Utility
